What is the electronic configuration for H2O?
Electron configurations are only made for pure elements. The electron configuration for Hydrogen is 1s1. The electron configuration for Oxygen is 1s2 2s2 2p4
What group attains Electron Configuration of noble gases by gaining one electron?
nitrogen will get noble gas configuration by adding three more electrons.
Why is the s-block called s-block?
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
What group of elements do not have an identical outer electron configuration?
noble gases Helium has 2 valence electrons, whereas the rest have 8.
Do ions have the same electron configuration as noble gases?
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
Which of these elements is found in a family with the above electron configuration?
Every elements have the electrons of an atom distribution or a molecule in molecular orbitals and it is called electron configuration. The element that can be grouped in the family with above electron configuration is called antimony.
How many valance electrons do most elements need to have a stable electron configuration?
8 valance electron
How many electron does barium have to give up to achieve a noble gas electron configuration?
Two electrons
What is the electronic configuration for H2O?
Electron configurations are only made for pure elements. The electron configuration for Hydrogen is 1s1. The electron configuration for Oxygen is 1s2 2s2 2p4
What is the electron configuration for boron?
1s2 2s2 2p1 is the electron configuration for boron, and it has a total of 5 electron. Just fill the orbital up with the elements total number of electrons until no more are left, then u have your electron configuration
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
How many electrons does group 7A need to become stable?
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
How does noble-gas notation shorten the process of writing an elements electrons configuration?
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
What group attains Electron Configuration of noble gases by gaining one electron?
nitrogen will get noble gas configuration by adding three more electrons.
Is the periodic table is most easily understood in terms of the electron configurations of the elements?
Yes. In terms of electron configuration and the number of valence electrons.
What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
